Abstract
There is disclosed a linear polarization to circular polarization converter. An outside surface of an inner conductor may be coaxial with the inside surface of an outer conductor. First and second diametrically opposed fins may extend outward from the outer surface of the inner conductor. Each of the first and second fins may include a conductive fin and a dielectric fin.
Claims14
A polarization converter, comprising:
- an annular waveguide comprising an inner conductor having an outside surface and an outer conductor having an inside surface coaxial with the outside surface of the inner conductor
- diametrically opposed first and second fins extending outward from the outer surface of the inner conductor, each of the first and second fins including a conductive fin and a dielectric fin, wherein
- each conductive fin is interlocked with the respective dielectric fin, and
- each conductive fin aligns and constrains the respective dielectric fin.
